Embodiment Construction

[0032] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. the embodiment. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0033] Such as figure 1 As shown, after the round steel pipe trusses 5 are installed in place, it is necessary to install the filling rods 8 between the two adjacent main pipes 501 on the two adjacent round steel pipe trusses 5. It is a saddle-shaped cutting surface (the size of the saddle-shaped cutting surface depends on the diameter of the main pipe and the filling rod), which ma...

Abstract

The invention discloses a traction device for installing vacancy filling rod pieces of circular steel tube trusses and a use method. The traction device comprises L-shaped arm rod; the ends, away from short arms, of the two L-shaped arm rods are arranged in a direct facing mode; a rotary winding device is arranged between the ends, away from the short arms, of the two L-shaped arm rods; pulleys are arranged at the ends, away from long arms, of the two L-shaped arm rods and the intersections of the long arms and the short arms; two traction ropes are wound around the rotary winding device; the winding directions of the two traction ropes are opposite; the free end of one traction rope sequentially winds around the two pulleys on one L-shaped arm rod, and the free end of the other traction rope sequentially winds around the two pulleys on the other L-shaped arm rod; and the free ends of the two traction ropes are used for being connected with main pipes of the two circular steel tube trusses which are arranged in a direct facing mode. According to the invention, the vacancy filling rod pieces can be precisely installed according to the design sizes, the construction period is shortened, hidden engineering dangers are eliminated, and relatively good economical efficiency is achieved.

Description

technical field [0001] The invention belongs to the field of civil engineering, and in particular relates to a traction device and a using method for installing a circular steel pipe truss truss filling member. Background technique [0002] In actual engineering, considering the installation process and the influence of closing temperature, after the round steel pipe truss is installed in place, there is usually a problem of rod filling. Especially for the intersecting circular steel pipe trusses, because the connection surface of the branch pipes is saddle-shaped, it is extremely difficult to install the gap-filling members of the adjacent circular steel pipe trusses. Traditionally, the method of shortening the blanking length of the blanking rod is often used, that is, through surfacing welding in the node area to make up for the lack of length of the blanking rod or to perform eccentric filling. This will cause the on-site installation to be inconsistent with the design,...
